The fore part is of one-piece constructionrand may be of any desired shape and size. Y rlhe heel part is divided longitudinally :from top to bottom into two sectioned-ai which Yare hinged together near the rear end oi' the heel, preferably on an axis extending diagonallyl downward and backward adjacent to the rear upper corner of the heel. Any suitable form of hinge may be employed, such as a pintle D passing through overlapping hinge members e-e formed on or car-j ried by the section z-a. These sections are thus rendered capable of moving laterally toward and away from each other at their front ends and bottom faces7 their opposed faces behind the hinge being slightly/cut away, and they are drawn together by a coil spring d extending transversely therein and secured at its ends to the respective sections. A transversely-extending pin c located inV alined recesses Vtormed in the sections a--af may be employed to Aguide them during their .lateral movements and strengthen the heel part against distortion under pressure exerted otherwise than laterally. f Vindicates the usual hole for the ack spindle., shown as formed inthe sections (z-a collectively. llhe mea-ns employ/editor detaehal connecting the tore part and the heel part Vare shown as consisting of a block 2 carried by the rear end o the :tore part and extending-upward and downward thereon, the side edges ot which block' are undercut to provide grooves adapted to receive the edges of a pair of plates 3--3 attached to the rontends of the sections w-a respectively. Behind the edges of the pla-tes 3-3 said sections are provided with a recess 4 adapted to' receive the block 2 and extend-V ing Vthrough the bottom of the heel pi rt, so that the latter can be applied by sliding it downward'on the slanting rearend of the -llore part.` Y rl`he parts when thus assembled are held together by the interlocking edges of the plates, 3 3 and the block 2,'which are preferably7 tapered upwardly to a slight extent. as shown.V Y Y lNhen'the heel part is applied-to the fore part as above described, it will evidently be enpandeal laterally to an extent depend!v ing upon the width and taper of the block 2 on the particular Atore part employed, and hence by providing each tore part with a block ci' a width and taper appropriate to 'the site oit' that :tore part the heel part can be caused to expand to the same width as the iore part to which it is attached, whatever the width of that :tore part may be. The rear end o1 each fore part is given an external outline corresponding to that of the Jfront end of the heel part up to the top oitx the latter9 so that when the heel part is applied to any tore part the external surgta ce ot the last is smooth and practically continuous throughout and a complete last of the desired size, width and shape is provided. Fig. 2 shows `in dotted lines the out lines olf tore parts which are respectively larger and smaller than that illustrated in full lines, together with the corresponding positions assumed by the heel part when applied thereto.

lt will be seen that the connection of the sections c fa by means of a hinge located near the top of the heel part enables the latter to expand throughout the length oi its lower portion, and that the diagonal arrangement ot 'the hinge causes such ei;- pansion to be somewhat greater at the front end ol the heel part than at its rear end. This is an important feature ot our inven tion. because it has the effect of causing1 the bottom portion of the heel part7 when e5:- panded to any given width, to correspond substantially in. outline with the appropriate sole pattern for that width throi'lghout the periphery of the heel.

The form ot last shown in Figs. 6 to ll inclusivej is oit the hinged-last type, the 'tore part and heel part being detachably connected. by means of, av transversely-extending' hinfre and cut away above the hinge to permit the last to be contracted longitudinally by an upward movement of the heel part with respect to the fore part. The

hinn'e member on the fore part is shown 'as consisting of a hollow metallic sleeve o set into andV held fast in a recess cut' in the fore part ot the last. behind which it er:- tends downward to the bottom of the last as at G. n liiove the extension 6 a gap 7 extends from end to 'end of the sleeve, which otherwise cylindrical internally. The cooperating hinge member on the heel part consists of two sul'istz'intially cylindrical projections 8 8 carried by the front ends ot the heel sections c c, one on each, and ding transversely in line with each r. so that they can be inserted endwise into or withdrawn from the sleeve 5 by a lateral movement of the heel part with relspect to the 'tore part and can turn circuin entially within the sleeve to a limited stent provided for by the gap 7. Said gap is less than half the circumference of the sleeve 5, so that the hinge members can be separated only hy a relative lateral movenient oit the fore part and the heel part. Consequently these parts remain connected after the last has been contracted longitudinally, and this constitutes an advantage over the arrangement shown in Figs. l and 2 for the reason that it enables the heel part to be used as a means for withdrawing` the 'tore part from a shoe after the last has been contract-ed.

recording to the arrangement shown in Figs. G to ll inclusive the sections a of the heel part are hinged together in the manner alreadv described and are expanded by means ci two pins 9 9 carried by the hinge projections 8 8 respectively and eX- ten-ding 'forward Vthereiircnn into a pair of ce responding slots l l0 cut in the sleeve 5. The lower ends of these slots connect with another slot ll which extends transversely through one end of the sleeve and is so located that when the heel part ot the last is swung' upward on the hinge the pro jecting1 ends oi" the pins 9 9 enter sa-id slot ll and can therefore slide along it when the heel part and the fore part 01"' the last are connected or disconnected. After Vthese parts have been connected and brought into proper lateral a-linement with each other the pins 9 9 .are `in position to enter the lower ends oi the slots l0 10 respectively, which slant upward and outward and there- Afore act to force the pins 9 9 Vapart and expand the heel part ot the lastwhen the Vzitter is swung downward. The angle of slant olt the slots 'lO-l0 will depend upon the sii/,e and width oit' the particular iiore part in which they are employech being such in each case-as to cause the heel part to `be expanded to a width corresponding to that et the fore part to which it is connected.

The 'form of last shofvn' in l2 `to 16 inclusive is similar to that just described en cept that a diiierent arrangement is employed for expandinv the heel part. ln this case the expanding pinsoand slots above described are omitted and the heel part is expanded by means o't-the narrow webs 15% 12 which connect the projections S 8 with the heel sec Aons L2-a2 respectively and are received within notches 13 13 formed in the upper edge'ot the sleeve 5 at its rear. These notches are so shaped as to provide oppositely-slantingg; tacos let-ld which enthe corresporiding:r edges of the'webs 1.2 12 and force the latter and the corresponding heel sections apart when swung downward. rllhe extent to which the heel part is expanded will evidently depend upon the distance betwee the notches l3 l3, which will vary accorningto the width ot the Atore part in which they are termed. illhen the heel part is swung upward the Y bottom face of the heel part when expand-` webs 12-12 rise above the notches 13e-13 and enter the gap 7 thus enabling the Vtore part and the heel part to be disconnected `by a relative transverse movement during which the webs move laterally in said gap.

In the terms of last already described the vlateral expansion or contraction of the heel y part takes place automatically when the lastV is expanded or contracted longitudinally, which we regard as desirable. This is not essential, however, since the heel part may be expanded laterally by means ot a device adapted to be, manually operated after the last has been expanded longitudinally. For example, in F igs. 17 to 21 inclusive is shown a lastin which the heelV part is expanded by means of a small rod 15 held by a staple 1G in a groove 17 which extends upward and downward in the rearend ot the fore part. The rod lcarries vat its upper end an outwardly-'projecting pin 18, which prevents Vit from passing out from under the staple when the fore part is detached, and at its lower vend it is tapered laterally to provide a wedge .19 adapted 'to enter between the front Vends of the heel sections @L3- a3 and wedge them `apart when the rod is forced downward'by hand, the wedge 19 being so proportioned, according to the width otV the fore part'which carries it, as to expand the` heel part to the corresponding width. The heel part and vfore part are shown as connected by atransverse hinge hereinafter, described.

Figs. 22 to 26 inclusiveshow a form of last in" which the heel part Vincludes two outer sections #wat and an intermediate section L5 arranged side by side, of which the two outer sections are movable laterally toward and away from the intermediate section to contract and expand the heel part and are located between top and bottom plates 20 and 21 .formed on or carried by the intermediate section. This construction has the advantages that the socket 7 for the jack .spindle canbe formed wholly in 'one section, (the intermediate sectiom) andthat the bottomV plate 21 prevents the exposure of gaps on the ed.V The pivotal connection between the heel part sections near their rear upper corners is shown as provided by slanting projections 22-,22 formed respectively on the inner facesY of the outer sections @t4-a4' and iitting'loosely within corresponding recesses 23-*23 cut in the intermediate section. a5, whereby, in connection with Vthe spring d, the outer sections are held in place and their lateral movements are suiiicientlyprovided for. The Vbottom V.plate 21'is given the proper peripheraljoutlinetor the heel part when'iully icontractec, 'and is upwardly beveled at its side and rear edges, so that the irregularities ot surface resulting from the expansion of the heel part are Vso slight that they Vare of no practical importance at the particular locations where they-occur.

Thev hinge connection. between the heel part and the tore part is shown in this case `oi? the recess 26 andV adapted to venter between wings 29Von the outer heel sections 'e4-a4, which wings are laterally beveled in correspondence'with the taper of the proiecti'on 28 and are spread apart by saidpro-v jection and thuscausedto expand the heel part when the latter is swung downward on the transversehinge. The extent of lateral expansion of the heel part will of course depend on the width oi? the projection 28, which will vary in correspondence with the widths of the diiterent iforeparts.

ln Figs. 27 to 82 inclusive .is shown another form of heel part having two outer sectionsV aG--e and an intermediate eetion a7, which are connected tothe fore part and expanded inthe saine way as in the form ot last last described. In this case, however, the formation of undesirably wide gaps in the bottom of the heel part when expanded is prevented by extending the lower portions of the outer sections cr-a6 late 1ally toward each other beneath the intermediate section a? and providing them with fingers 30 which are interleaved as shown in Figs. 29 and 30, so that the total space left between the outer sections vwhen expanded is divided into a number of small separate areas. YWhen this construction is employed the heel part sections need not be connected to one another by any hinge other than' that provided bythe interleaved fingers 30 and the spring (l, since said fingers maybe curved with respect to va common axis and slantedfromV top to bottom, as shown inrFigs. 27 and 30, in such manner that the guiding action of the fingersV will cause the heel part sectionseto move later lly 4with respect to a predetermined axis asa center, which center will preferably be located near the rear upper corner of the heel part for the reason previously explained. y

`The distribution et the gaps in the bottom of the heel lpart may be accomplished in another'way in theV manner illustrated in Figs. 33 to 39 inclusive, inwhich is shown a last having its4 heel part composed oi' two their rear upper corners as shown in Figs. (E, l2 and l?, and also detachably hinged to the tore part as shown in Figs. 27 and 28. Said sections all-a8 are expanded by means ot a rearwardly-tapering projection 31 formed -on the rear end of the fore part about midway between its sides and adapted to onto" between the beveled :tro-nt ends of the heel part sections d torce them apart when swung downward. ln this case the sections iL-a8 are so formed as to provide a longitudinal recess extended upward from the bottom of the heel part andv containing a number of vertical plates B2, which are loosely mounted on transverselyextending pins $53 and Sil and have their iront ends shaped to enter laterally-spaced grooves 35 iormed in the projection 3l. Springs 36 tend to torce the plates 32 together, as shown in Fig. 3G, but when the heel part is swung downward, said plates are spaced laterally Jfrom one another and from the sections aS--as by the grooves 35, as shown in Fig. 35. y

ln. Figs. l0 to ed: inclusive is shown another modification similar to that just described, except that the heel part comprises three main sections, of which the middle section a carries a top plate 37 overlying the outer sections alo-aw and contains the spindle socket t', and the supplementary gap-distributing plates 3S are located between the outer and middle sections andr mounted on a transversely-extending pin 39 carried by the'middle section al. The transverse hinge connection between the tore part and the heel part is similar to that "illustrated in Fig. 22,l except that the hook- `tliaped members turn in a sleeve 5 carried by the fore partand provided at its upper edge with a downwardlycxtending integral lip 2T which takes the place ot' the retaining plate 2T shown in Fig. 22. The expansion oi the heel part is effected in this case by providingthe outer sections ctw-aw with iorwaidly-extending tapered portions e() adapted to enter corresponding recesses al in the rear end ot' the fore part, and the middle section a9 and the plates 38 also have tapered front ends adapted toenter recesses 42 and in the fore part, whereby they are spaced laterally from one another and from the outer sections whenV the heel part is swung downward. lt will be understood, of course, that in this form of our last, as in all the others, the expanding means carried by eaclriore part will be so proportioned as to cause the heel part when fully expanded to have a width equal to that of such fore part at their adjacent ends.

ln connection with the various forms of our last above described we have illustrated in the drawings a number ot locking devices whereby the llore part and the heel part are held in expanded position while in use. Thus in Fig. l is shown a locking device consisting of a pinv la passing through one of the heel part sections near its upper iront corner and intoA 4the rear end of the fore part, whereby relative sliding` movement of said parts is prevented. The pin is inserted manually after the last has been expanded and is withdrawn when it is desired; to contract the last.

The locking device shown in Figs. (i to ll inclusive consists of a pivotally-mounted lever #l5 located in a recess formed in one of the heel part sections ci and having its forwardly-projecting front end provided with a notch 46 adapted toreceive the rear upper edge of the sleeve 5 when the parts are fully expanded, thereby preventing the Jfore part and the heel part from swinging on the hinge which connects them. The lever is automatically moved into lock'- ing position by spring 47 but can be readily unlocked by pressing downward on its iront end, which is exposed at the bottom of the gap separating the fore part and heel part.

In the 'form oi last shown in Figs. 17 to 2l inclusive the fore part and the heel part are locked in expanded position by means included in the hinge construction whereby said parts are connected. InV this case the hinge member carried by the fore part consists oi' a metallic sleeve 5 provided at its upper edge with a dowuwardly-extending lip 2?, as in Fig. et), and adapted to receive the hoolrlslraped members 25-25 on the sections of. Each of the members 25 is providecL with a downwardly-projecting pin 48 adapted to enter a slot el) formed in the sleeve 5/ and composed of a circumferentially-ezi1tending portion and a laterally-extending portion, the arrangement of which is such that when the heel part is laterally contracted the pins L18 are located in position to move in the circumferential portions ot the corresponding slots and the heel part can be swung upward or downward. Then the heel part swung downward and expanded by the wedge i9, however, the pins d8 enter the laterallyextending portions ot the slots 49 and acts as stops to prevent theheel part from being swung upward so long as it reimains laterally expanded. .fitter the last has been cont 'acted the heel part can be lifted upward sutliciently to withdraw the pins 48 from the slots 9, as shown in Fig. 20, wl'iercupon the hoolrsshaped members 25 25 can be slid laterally out oi' the sleeve 5 to disconnect the tore part and the heel part, their disconnection by av direct rearward movement of the heel part being` The locking device shown in Figs; 22 to 26 inclusive consists of a pivotally-mounted lever o() located in a recess formed in the intermediate heel part section @5, and provided at its forwardly-projecting front end Vwith a downwardly-extendingy hook 51 adapted to enter a Vperforation 52 in a plate 53 ksecured to the rear end of the fore part, the hook l51 being caused to engage the edge of said plate by a spring 54., The rear end of the lever 50 is located beneath the bottom of the spindle socket f and is accessible through a perforation55, so that the parts may be unlocked by inserting a small rod or f the like intofthe'socket f and perforation 55 and pressing it against the rear end ofthe lever 50. This form of locking device is particularly desirable because it enables the last to be unlocked by placing it on a special jack spindle having an unlocking` pin adapt- Vedito pass automatically through the peroration 55.

rlhe locking device shawn` in l? ig. 27 consists of a small bar 56 arranged to slide longitudinally in the iront end of the intermediate heel part section a7 and adapted to be moved upward against the pressure or' a spring 57 by meansofa forwardly-projecting pin 5S movable in a slot 59. The lower end of the bar 56, whenin its lowermost Y position, is received in a vertical slot 60 inl the rear end ofthe Jfore part and lies in front of a transversely-extending plate 6l carried by the fore part on its bottom face, and it will be evident that when said bar and plate are engaged, as shown in FigjQ, the fore .part and the'heel Vpart cannot turn Vonthe hingewhich connects them because the plate (Slis located in the path of movement of the lower end of the bar 56. Y i

Figs. 4.0 to 44: inclusive show another form of locking deviceof suchV construction that the .partsY of the-last can be automatically unlocked by placing the last ona jack spindle. In this casev the connection between the heel part and the :tore part consists of a `rod G2 4held between the middle heel part section 0,9 and one ofthe sections al and having laterally-bent ends,.oif"which the front end is adapted to enter a staple 63 carried by the iore part when the heel part is applied thereto. The rear end of said rod 62 is located in Y agroove ,64 formed in the heel part section downward inthe groove.

aV and so shaped that when the heel part is swung upward the rearV end of the rod moves Y A pivoted lever is normally held by a spring (36in such position that when the heel part is swung downward the rear end of the rod 62 slides upward` along saiddever and turns it on its pivot until the end of the rod passesabove the upper end or' the lever, whereupon the latter isthrown forward beneath the rod and prevents it from moving downward in the groove 6st, andsaid rod-` then serves as a fined strut to lock the heelpart and the tore part in their extended position. rEhe rear end of the lever 65 extends into the bottoni of thef spindle socket f, so that when the last is placed on the spindle the latter, if long enough, will turn the lever on its pivot and thereby release the rod62, leaving the latter free to move downward along the groove 64C. .Y

The last can then be collapsed longitudinally, the front endvof the rod 62 being withdrawn from the staple 63 when the heel part is detached from the fore part. d y

lt will be'observed that` in each form oi last-above described the heel part cannot be detached from the fore part until after the last has been contracted longitudinally, so

ing .devices shownin Figs. 6, 22, 27 and el() may be employed withoutsubstantial modilication in one orboth of the forms of last shown in Figs. l2 to 16 inclusive and Figs. 33 to 39 inclusive, in which no locking devices areshown. p

lt is. an advantage inherent in our last Vthat its withdrawal from a shoe formed on it is greatly lfacilitated by the lateral contraction of its heel part which precedes or accompanies the longitudinal contraction of the last and thus prevents the heel part from v binding in the rearportion of the shoe. In likemanner the subsequent introduction oit the last into the'shoe, if this becomes necessary, is facilitated by the fact that theheel part is laterally collapsed when it enters the top of theV shoe and is not expanded to its full width until it reaches the Vbottom ot the Y shoe. It will be obviousthat the employment of a spring or othermeans'for laterally contracting` the heel part of the-last is not atall essential, sinceV such contraction may be readily produced by external pressure suchlas isV exerted when the heel partis withdrawnfrom the shoe. j A
